摘要
网络控制系统是计算机、通信技术和控制技术融合发展所形成的一个新领域。网络诱导时延的分析与补偿是该研究领域的关键问题。分析了网络诱导时延,并建立了具有随机时延的网络控制系统在单包传输下的模型。然后引入全维状态观测器,在此基础上对系统的网络时延进行补偿。最后给出了不同情况下的仿真图,验证了时延的不利影响及补偿方法的有效性。
Networked control system (NCS) is a new study field that integrates computer communication technology and control tech-nology. The analysis and compensation of networked delays are the major concerns. First the random networked delays are analyzed,and the model of networked control system with random delay is developed in the case of single-packet transmission. Then we intro-duced an estimator to compensate the networked delay. Finally,the simulation in different situation has been given,which verifies the ...
